Perceived speed of moving surfaces following adaptation to motion, with variations in speed and texture

Data files include psychophysical measurements of perceived speed of moving surfaces that participants felt with their fingers. Judgements were made following adaptation to motion across the skin under various conditions (speed and texture were varied). Data files also include measures of contact force applied to the surfaces by the participants during the experiment. The data come from two experiments, both of which used a repeated measures design. Further description can be found in the associated publication, and in the readme file. The data files are tab delimited plain text, and are organised in the tidy data format (see http://vita.had.co.nz/papers/tidy-data.pdf) such that each variable forms a column, and each observation forms a row.

本数据集收录参与者通过手指触摸感知的运动表面主观运动速度的心理物理学测量数据。实验过程中，参与者先在多种调控了运动速度与表面纹理的不同条件下接受皮肤运动适应刺激，随后完成运动速度判断任务。数据集同时包含实验期间参与者对测试表面施加的接触力测量数据。本数据源自两项实验，两项实验均采用重复测量设计（repeated measures design）。更多详细说明可参阅相关学术出版物及数据集附带的自述文件（readme file）。数据文件采用制表符分隔的纯文本格式，并以整洁数据（tidy data）格式进行组织，详细规范可参见http://vita.had.co.nz/papers/tidy-data.pdf，其核心规则为每一列代表一个变量，每一行对应一条观测记录。
